COMBINED TYPE-WRITING AND PRINTING MACHINE.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed January 2, 1908.; Seria1;No.f, 409,026.

To all whom z't may concern:

Be it known that I, WILLIAM H. COLLIER, a citizen of the United States,residing at Jackson, in the county of Madison and State of Tennessee,have invented certain new and useful Improvements in a Combined Type-VVriting and Printing Machine; and I do hereby declare the following tobea full, clear, and exact description of the same, such as will enablethose skilled in the art to which it appertains to make and use thesame.

My invention relates to combined type writing and printing machines andinvolves lmprovements on and modifications of the machine of thatcharacter illustrated and described in my Patent No. 858,857, dated July2, 1907.

Machines of this class are particularly adapted for the printing ofcirculars, letters, etc., which are in the main the same but whichdiffer in minor respects, as for example, in the address.

The machine herein described is substan tially an ordinary typewriter towhich has been applied a printing bed adapted to enact with the platenof the typewriter to print from paper carried by said platen. In themachine herein described this printing bed is mounted to slide in thesame carriage upon which the saidplatenis mounted, said bed sliding in adirection at right angles to that of the movement of said carriage. Thisconstruction obviates any necessity of adjusting the carriage to anyparticular point with reference to the striking point of the typewritertype, before operating the printing bed. The same inking ribbon is usedfor making impressions from the typewriter type and from the type on theprinting bed, one end of this ribbon being preferably upon a reelmounted on the carriage. and the other end upon a reel mounted on thecarrier of the said printing bed, .means being provided whereby theribbon is fed automatically.

The objects of my invention are to improve the construction of thecombined typewriting and printing machines such as referred to; toinsure that the impression made by the printing surface of the saidprinting bed shall be made at the desired point on the paper on thetypewriter platen, and this without the necessity of setting thetypewriter carriage atany particular point; to improve the ink-ribboncarrying and feeding means of such machines; and generally to make themachine simple, compact and reliable and in general structure similar toan ordinary typewriter.

I will now proceed to describe my invention with-reference to theaccompanying drawings, in which one form of combined typewriter andprinting machine embodying my invention is illustrated, and will thenpoint out the novel features in claims.

In said drawings: Figure 1 shows a top view of my said combinedtypewriting and printing machine; Fig. 2 a side View thereof; Fig. 3 adetail top view of the printingbed carrier; Fig. at shows a detailsection through the ribbon carrying reels and platen: Fig. 5 shows adetail section from front to rear through the platen carriage andprinting bed. the platen being shown elevated; and Fig. o-shows asimilar view,

the platen being shown lowered into oper- 'ter of that shown in my saidPatent No.

858,857, namely the machine known on the market as the Smith Premiermachine, certain modifications having been made in the said machine toadapt it for carrying a printing bed. Since the said machine is wellknown, and since also my invention is equally applicable to most of theother commercially known typewriters, I have not illustrated in full themechanism ofsuch machine, and particularly have not shown many of theparts and sub-mechanisms of such machine which are in no wisefafiectedby the application of my invention to the machine. i

It will be understood that I do not limit myself to the use of myinvention on any particular make of typewriter.

In the drawings 1 indicates the frame of I the machine, 2 the key boardthereof and?) the usual wires connecting the keys of said key board tothe type bars (not shown) of the machine.

4 designates the platen carriage, mounted prised in said to slidelaterally of the machine on ways 5, and 6 designates the usualtypewriter platen. For simplicity of illustration I have not shown, inconnection with this laten, -the usual paper holdin and aper eedingdevices, but it will die un erstood that the platen and platen carriageare provided with such devices.

7 is the said printing-bed carrier and 8 the printing surface thereof. Ihave not illustrated any particular type surface as comrinting surface,but -customarily the surface will be one comprising type-faces, such forexample as the surface produced by assembled types or a stereotypeplate. The rinting-bed carrier 7 is mounted to. slide f fom front toback in the platen carriage 4 itself, the printing surface 8 on saidcarrier being at such height that when said carrier is moved forward asdescribed, said surface will press the inking ribbon 9 (Figs. 4, 5 and6) against paper on said platen and so will print an impression on suchpaper. When said carrier is in its extreme rearward position its frontpart is in front of the platen and therefore there is in said carrier anopening 10 in front of the printing surface 8 through which the typebars of the typewriter may strike the ribbon against the paper on theplaten 6, the same as in an ordinary typewriter- One end of the ribbon 9is upon a reel 11 mounted to rotate upon the platen carriage andprovided with a return spring 12 tending normally to wind the ribbon upon said reel. The other end of the ribbon is upon 1 a reel 13 mounted inbearings at the front end'of the printing-bed carrier 7. It'will be seenthat as this carrier 7 is moved forward, the said ribbon 9 will movewith it, passing the paper on platen 6 at the peripheral speed of saidpaper and (what is the same thing) at the speed of movement of theprinting surface 8, and so causing no blurring on the paper; and it willalso be seen that upon the backward movement of the said printin -bedcarrier the ribbon will return and wild be wound up again on said reel11. To feed the ribbon forward slowly from reel 11 to, reel 13, Iprovide fee'ding mechanism comprising a worm wheel 14 on said reel 13, aworm' 15 mounted in hearings on said carrier 7 and engaging said wormwheel, a ratchet wheel 16 on said worm, and a ratchet pawl 17 arrangedto engage a tooth of said ratchet wheel 16 during each backward movementof said carrier 7 and near the end of such backward movement, sorotating said reel 13 intermittently and thereby winding the ribbonslowly from the one reelto the other.

In some cases it is desirable to be able to make an insertion at somepoint in the body of the matter to be printed by the printing surface 8.In such case an opening similar to opening 10 may be left in the carrier7 and printing surface, where such insertion is to be made. In Fig. 1 Ihave indicated such an opening at 18.

What I claim is 1. In a combined typewriter and printer the combinationof a typewriter platen, a carriage therefor, a frame, typewriterprinting mechanism, and a printing bed movable with said platen carriageand movable with respect to said carriage in a direction transverse tothe axis of rotation of said platen.

2. In a combined typewriter and printer the combination of a typewriterplaten, a carriage therefor, a frame, typewriter printing mechanism, anda printing bed movably mounted in said platen carriage to move in adirection transverse to the axis of rotation of said platen.

3. In a combined typewriter and printer the combination of a laten, acarriage therefor, a frame, typewrlter printing mechanism, a printingbed movable with said carriage and movable in a direction transverse tothe axis of rotation of said platen,

riage, another ribbon carrying reel mounted on said printing bed, one ofsaid reels provided with automatic return means, and

feeding means engaging the other of said wheels.

5. In a combined typewriter and printer the combination of a laten,- acarriage therefor, a frame typewriter printing mech-' anism, a printingbed movable with said carriage and movable in a direction transverse tothe axis of rotation of said platen, a ribbon carrying reel mounted onsaid platen carriage and provided with automatic return means, anotherribbon carrying reel mounted on said printing bed and ratchet mechanismfor feeding the ribbon comprising a ratchet wheel mounted on saidprinting bed and a pawl adapted to engage said reel.

6. In a combined typewriter and printer, the combination with the rotaryand axially movable platen and printing mechanism of a typewriter, ofpriilting means comprising a support for a printing surface incooperaplaten and in a direction transverse to the In testimony whereofI aflix my signaads of lgtathin (if saild platen, and also to ture, inthepresenoe'of two witnesses.
